To all whom it may concern:

Be it known that we, Hi-zmnzn O. EKERN and \ViLLL-lni L. EKERX, citizens of the United States,residing at Flandreau, in the county of Moody and State of South Dakota, have invented certain new and useful Improvements in Portable Garage (arrease-Guns; and we de hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which 1t ap pertains to make and use the same.

Thisinvention has for its object to provide a gun of improved and simplified construction specially designed for forcibly ejecting heavy oils and greases such as used for lubricating the transmissions and differential of motor vehicles.

Another object is the provision of a simple and etlicient indicating device for indieating the quantity of oil or grease ejected from the gun. \l'ith th above. and other objects in view, the. invention consists in the novel construction. arrangement and formation of parts as will be lua'einat'ter specifically described, claimed and illustrated in the accompairving drawing. in which:

Figure 1 represents a vertical central sectional view through a grease gun constructed in accordance with this invention. Fig. :3 represents a horizontal sectional view on the line 2-2 of Fig. 1. Fig. 3 represents a horizontal sectional view on the line 3- 3 of Fig. 1. looking upwardly. Fig. l represents alragmental detail sectional view through a portion of the grease. gun illustrating the spring retaining means for the slide rod;

l'leterring to the. drawing in detail. wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates a base provided with a plurality of radially directed legs (3 carrying casters 7 at their outer extremitie whereby the grease gun maybe conveniently moved from place. to place. The central portion of the base 5 is formed with an annular depression or seat in which isengaged the casing or cylinder tiot' the gun communicating with a passage 9 formed in the base 5 for conducting the material ejected from the gun. The casing S is sccured in position upon the. ,base 5 by a plurality of bolts or connecting rods ll) posi tioncd at their upper extremities through an annular llange ll of the casing 8. ()ne of .operation may be determined.-

the rods 10 provides a pivotal bearing for a frame structure 12 in ,.which .is rotatably mounted a horizontally disposed shaft 13 carrying an operating crank ll at its outer end. The lower bar of the frame 12 is adapted to rest upon a post 15 carried by the casing b and on which is pivot-ally secured a U-shaped strap 16 adapted to be the piston rod 1b and is formed integral with a collar or-tlange. 21 having internal Stl'(\\'l illt;lllfi 'litting the threads of 'the piston rod 18. The bevel gear wheel 2() is in permanent mesh with a bevel gear wheel :22 carried by the horizontally disposed shaft Z3 'lhobevel gear "20 and its collar or flange til-are mounted between the upper .and lower horizontal bars of the frame 113 and are thus prevented from moving vertically rela-"e to the casing 8 during the operation of the gun. A rod is slidably mounted through an 'al'iertured ear formed integral with the frame 12 and is disposed parallel with the piston rod 18.

The rod 12+ is retained in adjusted position by a spring actuated plunger :26 positioned in a recess formed in the ear :25 and is "formed with an angularlv directed uppcn' extremity 27 preferably enlarged and formed with a rectangular opening 2b in which isslidably and non-rotatably positioned an indicating block if) rotatably mounted at 3 in the upper extremity of the threaded .piston rod 1'8. The opposite Faces of the block 2 are preferably formed with suitable markings, whereby the movement of the piston rod 18 relative to the. angularly directed end 27 of the rod Q-l may be quickly ascertained and thus the quantity ol material ejected from the gun during its it is clearly evident that any portion of the contents of the car-ding 8 may be ejected and in any desired quantity. which may be accurately determined by releasing and moving the rod :2! downwardly until it is stopped by engagemcnt \\'lt'll the top face of the piston 17 7:!
